Just a suggestion for future grows…
May want to start working in some insect frass into ur grows, roach and cricket are most ideal, mealworm can be good too but the presence of chiton will keep ur plants defenses up thinking it’s under attack so when an infestation does hit it can protect itself and naturally fight it off(to a certain extent)
As far as one plant being gone savage on and the other untouched, it’s certain smells certain bugs can have an attraction to, had ant issues this year that they just would not leave 3 plants alone out of 25 that I had to intervene and fight em off so it’s that certain genetic that they absolutely love and have a heavy attraction to from whatever smells they are picking up from it
That’s where the chiton and insect frass can slightly change ur plants chemistry enough it’s no longer appealing to the pests
I def wouldn’t suggest the strain for future grows if it’s a mite magnet or expect to do some serious ipm watching closer for another grow of it
